• Chapter 1 Introduction to Micro Economics

  This chapter introduces the basics of microeconomics, emphasizing its importance in analyzing specific markets and guiding individual decision-making. It distinguishes microeconomics from macroeconomics, focusing on smaller economic units like households and firms. The chapter explores core economic problems such as what to produce, how to produce, and for whom to produce, which arise due to the scarcity of resources. Concepts like opportunity cost and the production possibility frontier (PPF) are discussed, highlighting their role in efficient resource allocation. By understanding these principles, students can grasp how individual decisions influence resource utilization and the broader economy

• Chapter 2 Theory of Consumer Behaviour

  This chapter explores how consumers make choices to maximize their satisfaction with limited resources. It introduces utility, distinguishing between Total Utility (TU) and Marginal Utility (MU), and explains the Law of Diminishing Marginal Utility, which states that satisfaction decreases with each additional unit consumed. The chapter also covers the consumer's budget and budget line, showing the combinations of goods a consumer can afford. It delves into indifference curve analysis and the Marginal Rate of Substitution (MRS), which illustrate consumer preferences and trade-offs. Finally, it explains consumer equilibrium, where satisfaction is maximized, providing a foundation for understanding consumer behavior and its effect on market demand.

• Chapter 3 Production and Costs

  This chapter explains the production function, highlighting short-run and long-run production. It introduces the Law of Variable Proportions and returns to scale to describe output changes. On costs, it discusses fixed, variable, total, average, and marginal costs, emphasizing the relationship between cost curves. It lays the foundation for understanding production processes, cost structures, and decision-making for efficiency.

• Chapter 4 The Theory of the Firm under Perfect Competition

  This chapter explores the functioning of firms in a perfectly competitive market with many buyers and sellers, homogeneous products, and free market entry and exit. It introduces key revenue concepts like total revenue (TR), average revenue (AR), and marginal revenue (MR), emphasizing firms as price takers. The chapter explains profit maximization, achieved when marginal cost equals marginal revenue, and differentiates between short-run and long-run equilibrium. It provides insights into market efficiency, resource allocation, and competition dynamics in perfect competition.

• Chapter 5 Market Equilibrium

  This chapter explains market equilibrium, where demand equals supply, determining price and quantity. It explores how shifts in demand or supply and government interventions like price ceilings and floors affect equilibrium. The role of the price mechanism in efficient resource allocation and market stability is also highlighted.

• Chapter 6 Non-competitive Markets

  This chapter covers non-competitive markets, including monopoly, monopolistic competition, and oligopoly, focusing on price control, entry barriers, and product differentiation. It explains firms' profit-maximizing strategies, their impact on consumers, and the role of government regulation in curbing unfair practices.
